可以參考
http://www.spuler.us/apollo/index.html# 最下面的 "Theme Options" ,簡單說是用 theme 改 CSS 。
看看這段 Apollo theme 裡的 throbber.css:
代碼:
#navigator-throbber {
list-style-image: url("chrome://global/skin/subskin/throbber32.png") !important;
}
#navigator-throbber[busy="true"] {
list-style-image: url("chrome://global/skin/subskin/throbber-anim.gif") !important;
}
toolbar[iconsize="small"] #navigator-throbber,
toolbar[mode="text"] #navigator-throbber {
list-style-image: url("chrome://global/skin/subskin/throbber16.png") !important;
}
toolbar[iconsize="small"] #navigator-throbber[busy="true"],
toolbar[mode="text"] #navigator-throbber[busy="true"] {
list-style-image: url("chrome://global/skin/subskin/throbber16-anim.gif") !important;
}
其實語法不難,只要修改 url 然後把這些 css 加到 userChrome.css 應該可以。不過我沒試過,您成功了說一聲喔!
